One of the three types of mind.
"The Inner Mind is fundamental for the direct experience of the truth. Undoubtedly, the Inner Mind creates its basic concepts with information contributed by the Superlative Consciousness of the Being. Unquestionably, the Consciousness can live and experience reality. Without a doubt, the Consciousness knows the truth. To manifest itself however, the Consciousness needs a mediator, an instrument of action, and this in itself is the Inner Mind. Consciousness knows directly the reality of each natural phenomenon and can manifest it through the Inner Mind... One who has opened the Inner Mind recalls one’s previous existences, knows the mysteries of life and death; not because of what one has or has not read, not because of what someone has or has not said, not because of what one has or has not believed, but because of terribly real and vivid direct experience." - Samael Aun Weor, The Great Rebellion
